Construction tips and tricks
Physically wiring the sensors together, into a suitable enclosure, is always a little tricky. There is no right or wrong way, but here are some tips and tricks.
This is a Draft - I am still working on it.
Notes to include
- 4k7 on DS18B20
- Voltage divider on battery sensors
- Short headers
- Multi-layer heat shrink
- staggered junctions
- Tool for wires
- Velcro straps around battery
- The new XH connectors I just found (if they work well)
- Foam to pack
- Velcro ties
- A collection of images I plan on writing about ...
Enclosures
There are two kinds of enclosures I've used. The first are small ABS boxes. I typically use this store but suitable boxes should be available locally,
Things to look for
- fixing flange so it can be screwed or hung or ziptied easier
- screws in 4 corners to ensure fits tightly on cables in notches (this is less common)
Alternatively, I use 40mm PVC pipe, with end caps. These should be available locally.
Cables in boxes
- Bring cables out next to screws if box only screwed diagonal
